About Telaglenastat

Telaglenastat is an investigational first-in-class, novel glutaminase inhibitor specifically designed to block glutamine consumption in tumor cells. RCC tumors commonly exhibit metabolic alterations that increase their dependence on glutamine. In preclinical studies, telaglenastat produced synergistic antitumor effects when used in combination with standard-of-care RCC therapies. On June 17, 2019, Calithera announced that a randomized Phase 2 trial of telaglenastat plus everolimus versus everolimus plus placebo (ENTRATA) met its primary endpoint of improving progression free survival, demonstrating proof of concept for telaglenastat in patients with advanced RCC. The ongoing CANTATA trial is a global, randomized, double-blind trial designed to evaluate the safety and efficacy of telaglenastat plus cabozantinib versus placebo plus cabozantinib in patients with advanced or metastatic RCC.

About INCB001158 (CB-1158)

INCB001158 (CB-1158) is an investigational first-in-class, novel small molecule arginase inhibitor. Arginase is an enzyme that suppresses the immune-mediated destruction of tumors by depleting levels of a key amino acid, L-arginine, from the tumor microenvironment. A number of cell types in the tumor microenvironment, including myeloid-derived suppressor cells, macrophages, and neutrophils, can secrete arginase. L-arginine deprivation can act via nutrient sensor pathways to exert several suppressive effects on T-cell function, inhibiting proliferation, decreasing cytokine production, and diminishing expression of the T-cell receptor CD3ζ chain. Arginase activity may thus impair T-cell mediated anti-tumor responses. INCB001158 is being developed in a global collaboration with Incyte Corporation.
